Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162770, here are decompositions:

  • 19 + 162751 = 162770
  • 31 + 162739 = 162770
  • 43 + 162727 = 162770
  • 61 + 162709 = 162770
  • 67 + 162703 = 162770
  • 79 + 162691 = 162770
  • 193 + 162577 = 162770
  • 241 + 162529 = 162770

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 162,770 and was likely granted around 1874.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 162770 first appears in π at position 148,001 of the decimal expansion (the 148,001ordinal-suffix:st digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
